进入插件管理->Advanced,修改Update Site的URL,路径为“http://mirror.xmission.com/jenkins/updates/update-center.json”,(注意不是https), 修改完成,submit,然后checknow(如果浏览器一直在转圈加载, 可稍微等几分钟, 再刷新浏览器也好了, 我的就是这样…)。问题解决。

感谢@QA1175133706 在博客: https://blog.****.net/LANGZI7758521/article/details/100099384 评论中提供的网址, 我试了第一个就可以, 谢谢. 以及用了上面博客作者的一张图, 谢谢.

最后说明下:
看到很多人抱怨修改成: http://updates.jenkins.io/update-center.json 无用, 我试了, 确实没用…悲剧. 但我并无诋毁上述博客作者之意, 望理解.
